Abstract: A refrigerator includes a first tray assembly defining a portion of an ice making cell, a second tray assembly defining another portion of the ice making cell, a heater disposed adjacent to at least one of the first and second tray assemblies, and a controller configured to control the heater. The refrigerator further includes a pusher having a first edge pressing the ice or at least one of the first and second tray assemblies to separate the ice from the tray assemblies, a bar extending from the first edge, and a second edge disposed at the end of the bar. The second tray assembly includes a first coupling part connected to the pusher and a second coupling part connected to the driver. The controller moves at least one of the pusher and the second tray assembly to change a relative position between the pusher and the second tray assembly.
